Electric Field Area and Wind Volume Change of Industrial Electrostatic Precipitator
In general, the electric field can be divided into six areas, namely, three charged areas and three dust collecting areas. The charged areas are always in front of the corresponding dust collecting areas and three dust collecting areas, and the charged areas are always in front of the corresponding dust collecting areas.
In the first and second charged electric fields of industrial ESP, the dust is thick because of the high concentration of smoke and dust. The improved RS dense barbed wire is the best cathode. The combination of pulse power supply and RS dense burr wire can obtain the best charging effect.
Because when RS dense burr wire works, the burr tip can produce strong corona discharge, strong ion current can destroy negative space charge effect, avoid corona closure, and provide pulse power supply at the same time can prevent the generation of anti-corona. They complement each other and form a charging area with complete power supply structure, strong adaptability to flue gas operating conditions and strong charging effect.
For industrial electrostatic precipitator, besides its electric field, there are also changes in the air volume of its induced draft fan. The change of air volume has little effect on the equipment, but the dust removal efficiency of industrial electrostatic precipitator changes obviously with the change of air volume.
If the wind volume increases, the wind speed in the electric field of ESP increases, so the residence time of dust in the electric field is shortened. Although the wind disturbance in the electric field enhances the effective driving speed of charged dust, it is not enough to compensate for the negative effects of the shortened residence time of dust in the electric field caused by high wind speed and the intensification of secondary dust. Therefore, the efficiency of dust removal decreases obviously; on the contrary, the efficiency of dust removal increases, but the increase is not significant. The change of air volume of dust collector is very important for the effect of dust removal.www.icleairs.com
